easypoi excel file import and export

 

1. Introduction of POM

 

         <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-base</artifactId>
            <version>3.0.3</version>
        </dependency>
        <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-web</artifactId>

Second, excel file export

 

2.1 Physical Design

public  class Sku {
    @Excel(name = "skuNo",orderNum="0")
    private String skuNo;
    
    @Excel(name = "soldTo",orderNum="1")
    private String soldTo;
    
    @Excel(name = "hubId",orderNum="2")
    private String hubId;
    
    @Excel(name = "soldAllocation",orderNum="3")
    private String soldAllocation;

    @Excel(name = "hubAllocation",orderNum="4")
    private String hubAllocation;

 

Add a comment to the field that needs to be generated to excel, and then set num, starting from 0

 @Excel(name = "生日", orderNum = "8", importFormat = "yyyy-MM-dd") 

 

2.2 Export

@Test
    public void test() throws Exception{
        
        List<Sku> list = new ArrayList<>();
        for (int i=1; i<10000; i++) {
            Sku s = new Sku ();
            s.setHubAllocation("hubAllocation" + i);
            s.setHubId("hubId" + i);
            s.setSkuNo("skuNo"+ i);
            s.setSoldAllocation("soldAllocation" + i);
            s.setSoldTo("soldTo"+ i);
            list.add(s);
        }
        Date start = new Date();
        Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams(),
                Sku.class, list);
        System.out.println(new Date().getTime() - start.getTime());
        File savefile = new File("D:/excel/");
        if (!savefile.exists()) {
            savefile.mkdirs();
        }
        FileOutputStream fos = new FileOutputStream("D:/excel/SKU.xlsx");
        workbook.write(fos);
        fos.close();
    }

 

2.3 Test Results

 

 

3. Import and parse the file into the database

3.1 Physical Design

 

public  class Sku {
    @Excel(name = "skuNo")
    private String skuNo;
    
    @Excel(name = "soldTo")
    private String soldTo;
    
    @Excel(name = "hubId")
    private String hubId;
    
    @Excel(name = "soldAllocation")
    private String soldAllocation;

    @Excel(name = "hubAllocation")
    private String hubAllocation;

 

Description: Import does not need to specify num column number

 

3.2 Import

@Test
    public void test2() {
        ImportParams params = new ImportParams();
        params.setTitleRows(0);
        params.setHeadRows(1);
        long start = new Date().getTime();
        List<Sku> list = ExcelImportUtil.importExcel(
           new File("D:/excel/SKU.xlsx"),
           Sku.class, params);
       
         System.out.println(new Date().getTime() - start);
        System.out.println(list.size());
}

 

Description: setTitleRows(0) sets the position of the column title, such as

 

 rows should be set to 0
